You are right, it depends on the situation. I mean that the
details, like PLATFORM and COMPILER, should be
hidden for the user by default. E.g., it _could_ be that we
have 2 expat implementations:

   xml/impl/expat/win32
   xml/impl/expat/unix

No need to bother user with platform details in this case.
